I seen a drilling fixture with blanks for sale but I cant remember who sells it. I have a Quickfuel 1050 4150 style carb and it's lean according to my plugs. When I install the wide band I'm sure I can get it where it needs to be because everything is adjustable on this carb. I've got a few chunks of aluminum that I could make my own drilling fixture but that other deal comes with blanks with a small pilot hole in them.
